Double-page spread - design alterations

Once I had finished my design for my double-page spread, I took some feedback from people who were included in my target demographic. The main criticism I received was that the electric blue colour used in my design idea didn't follow the metal style visually, and it also didn't follow my colour scheme. I will alter the design so that it will fit my colour scheme, and follow the metal visuals, by changing the colour scheme from electric blue to blood red.
